Problems solved by technology

Therefore, some food-inducing agents should be added to the feed. Its function is to improve the palatability of the compound feed, lure and promote the ornamental fish to take the feed actively; the stable feed requires that it should not be loose in the water for a certain period of time, so that the fish can eat and prevent nutrients At the same time, feed collapsing in water will cause water pollution and affect the normal growth of ornamental fish; the body color of ornamental fish fed with colorant pellet feed is often not as bright as that of ornamental fish fed with natural bait, which will affect its commodity value and viewing Value, adding colorant to the feed can improve the color of the fish body, the commercial value of ornamental fish, one of the very important indicators is the color of the fish body, once the fish body loses its bright color, it will reduce its appreciation value

Embodiment 1

[0017] The feed for ornamental fish is obtained by adding cereal gluten coarse powder and astaxanthin powder with a weight ratio of 5% to amino acid fermentation broth medium, fully mixing, extruding and granulating after drying.

[0018] Described astaxanthin powder is obtained by following method:

[0019] ① After drying the shrimp and crab shells, soak them in acetic acid until softened, then wash and dry;

[0020] ②Crush the softened and dried shrimp and crab shells, pass through a 150-mesh sieve, and then use protease hydrolysis to remove protein under the condition of pH value of 2-3 and temperature of 40-45°C;

[0021] ③ Add dichloromethane to the deproteinized shrimp and crab shell powder, and process it with 2000-3000MHz ultrasonic wave for 10-30min, and control the temperature at 30-35°C, and filter to obtain the crude astaxanthin extract;

[0022] ④ suction filter the astaxanthin crude extract, and the filtrate is heated in a vacuum water bath to remove residual me...

Embodiment 2

[0025] The feed for ornamental fish is prepared by adding cereal gluten coarse powder and astaxanthin powder with a weight ratio of 10% to the separation liquid in the amino acid fermentation broth medium, fully mixing, drying, and then extruding and granulating.

[0026] Described astaxanthin powder is obtained by following method:

[0027] ① After drying the shrimp and crab shells, soak them in acetic acid until softened, then wash and dry;

[0028] ②Crush the softened and dried shrimp and crab shells, pass through a 150-mesh sieve, and then use protease hydrolysis to remove protein under the condition of pH value of 2-3 and temperature of 40-45°C;

[0029] ③ Add dichloromethane to the deproteinized shrimp and crab shell powder, and process it with 2000-3000MHz ultrasonic wave for 10-30min, and control the temperature at 30-35°C, and filter to obtain the crude astaxanthin extract;

[0030] ④ suction filter the astaxanthin crude extract, and the filtrate is heated in a vacuu...

Abstract

The invention relates to an ornamental fish feed, and belongs to the technical field of ornamental fish culture. The ornamental fish feed is prepared by adding grain bran meal and 5 to 10 weight percent of astaxanthin powder into amino acid fermented broth culture medium or separation solution thereof and performing full mixing, drying, extrusion and granulation. The ornamental fish feed has excellent performance on the aspects of nutrition, palatability, stability and colorant, and is very suitable for ornamental fish culture.

Description

technical field [0001] The invention relates to a feed for ornamental fish, which belongs to the technical field of ornamental fish breeding. Background technique [0002] The preparation of ornamental fish pellet feed should pay attention to the following aspects: nutrition, nutrition and palatability are the most important indicators of the quality of the feed. In terms of nutrition, it can be divided into two parts: growth and color enhancement. The content of nutrients should meet the requirements of Ornamental fish growth demand standard; palatability The different odors emitted by the feed are an important basis for the preliminary identification of the quality of the ornamental fish feed. Generally speaking, a good feed emits a fishy smell and fragrance with a seafood taste. Therefore, some food-inducing agents should be added to the feed. Its function is to improve the palatability of the compound feed, lure and promote the ornamental fish to take the feed actively; ...
